To all whom it may concern:-

Be it known that we, MARTIN B. LnAvnNs and HERBERT D. VVILsoN, citizens'of the United States, residing at Los Angeles, in the county of LosAngeles and State of California, have invented a new and usefulExhauster for Original Commercial Containers, of which the following isa specification. f r

The primary object of this invention is to provide an exhauster forcommercial hard grease containers so that the contents of an originalcontainer may be easily and conveniently forced therefrom.

,Another object of the invention is to provide an exhauster of thisnature which is adaptable to varlous slzed contalners.

Another object of the invention is to provide a device which may bequickly connected to a commercial container of grease in such fashionthat the grease may be forced therefrom through a spout.

With these, and other objects, in view the invention consists of certainnovel features of construction, .combination and arrangement of parts,as will be hereinafter fully described, illustrated and claimed.

In the accompanying drawings: Figure l is a longitudinal sectional viewthrough the exhauster and container; Fig. 2 is a side elevation, partlyin section showing the plunger forced about midway of thecontainer;

. Fig. 3 is a section on the'plane of line 3-3 of Fig. 1; Fig. 4 is asection on the plane of line H of Fig. 1; Fig. 5 is a perspective viewof the spring expansion ring used in connection with the plunger.

Referring in detail to the drawings by numerals: 1 designates anoriginal commercial container for hard grease and similar substances. Athreaded shaft 2 extends longitudinally through the container and isconnected at one end to a plate 3 having a spider-like center formed bythe arms 4 and ring 5. The shaft 2 projects through the ring 5 and isconnected at its terminal to a washer or disk 6 which limits themovement of the shaft in one direction. A spout 7 is connected to theplate 3 around the central spider portion by means of an internallythreaded flange 8 into which the spout threads. An adjustable head orplunger 9 is employed to force grease from the container 1 and thisplunger which is preferably made of canvas is held taut and into closeengagement with the inner side of the Specification of Letters Patent.

container by a spring expansion ring 10. The ring is split as shown inFig. 5 and may be fitted into cans or containers of differentdiameters.f

The plunger is strengthened and reinforced by a follower 11 in theformof a cir 1 cular plate. The plate is centrally apertured to permit thepassage ofthe threaded shaft 2 and is provided with an outwardlyextending internally threaded neck 12 through which the shaft 2 alsoextends. A plurality of fingers 13 are held. slidably in engagement withthe outer side of the followerby straps 1 1 and these-fingersareprovided on their inner terminals with teeth 15 to catch in theoutwardly facing teeth 16 of the follower and prevent inward movement ofthe fingers. The fingers areprovided on their outer ends with extensions17 which engage the lower edge of the expansion ring 10 and forcesaidring inwardly along with the follower-4 A removable hand wheel. 18 fitsover the outer endof the shaft 2 and is held against rotation relativethereto by means of the squared portion 19 of the shaft. This wheel ispreferably made hollow so as to inclose the pointed end 20 of the shaft.

.When it is desired to force grease from .a commercial container such asindicated by the numeral 1, the shaft 2 is forced through the bottom ofthe container and worked about so as to form an enlarged opening 21through which the grease is discharged. The top is then removed from thecontainer and the plunger 9 and follower 11 fitted into position asshown in Fig. 1. The fingers 13 may be forced outwardly so as to fitvarious sizes of containers. hand wheel 18 is slipped over the outer endof the shaft 2 and the shaft turned by means thereof the follower andplunger will be drawn inwardly to expel the contents of the container.

In order to conveniently handle a commercial container of grease whenour exhauster is applied thereto a band 21 having a handle 22 is clampedaround the body of Now when the tion with commercial containers ofvarious port said spring means.

method of utilizing said contents:

Although we have shown and described the preferred embodiment of ourinvention, it will be'understood that minor changes of construction andarrangement of parts may be made without departing from the scope andspirit of the invention as claimed.='

'What we claim is:
